" JAcK w; PUTERBAUGH, or} 'qmemmwmmo MIXING mc'nrnn dMyiin'vention relates to mixing machines. of' the typesuitable for whipping cream, l

mixing machines heretofore onfthe market 10 to obtain enough; flufling up of. the product. It has often been'the practice for a manufac turer to supply two machines, one for doing [I e [the body of the whipping, and the 'otherfor' flufiing up the product-sufiiciently for the 1 trade requirements after the; main body of l the mixing has been accomplished.

i Broadly it is the object of myinvention to provide a machine-which will thoroughly I 7 ix and churn and give-the desired aeration, and, at the same time, impart a desired fluffiness during-the rnixing operation;

V ,Specificallyit is my cb eetto provide agitator in a mixing machine having one or moremlxlng blades or devices which, during "'3 the rotation ofthe miiteragitator'in one di rection,'impart suiiicient movement ofucurrents counter to the'main direction offiowto cause a desired flufi'ingup. It-is-also myob ject to provide .ian agitator in which the I blades or deviceswhich'impart the countercurrents have movement imparted thereto by contact with the mixing mass of niaterialf I l in the drawings are mounted thereon; The

agitatorsare'composed of hubplates 18 ro-j;

tatably mounted injspaced position" on: the 85 shaft" 17 and blades orwires 19 extend dutin convex for:nations" from the peripheries of f within the mixer.

, The above and other objects to ,which refl 3- 'erencewill be made in the ensuing disclosure I accomplish by that certain combination and i arrangenlent of parts of whichI have shown a preferred modification. I Referring to thedrawings:

It vwill of c0urse,].be'v entirely 1 practical to mounta driving pinion on the shatt -lgandj drive the mixerbymeansjof 'a i I i sn allelectr'ic motor; 'l V i The j agitator shaft through and the agitating dcvi ces indicated v a one on each side of the 'shaftl'i and thereby r forming open 1 baskets having curved exteriors. v- While I have shown asimple single wire mesh formation, it-will' be within the iscopeof my invention to provide cross Wires o v anda'more elaborate basket formation'which'v may be desirable for: certain types of mixing work;v

material to be niixedup to such a point as will f about half .waysubmerge the agitating do? vices. When the" mixer shaft is rotated a YFJFE QEJ hasiafixed cross shaft soil 17 mounted in an aperture extending gtheree l main current of mixing material will be formed by the passage of the wires 19 throu h the material. Meanwhile the rotation of t 1e shaft will cause the blades of the agitating 5 devices to revolve in opposite directions when viewed from the same point on the shaft 17. The rotation of the agitating devices in spherical fommtimr or currents havinghorizontal" axes will be constantly carrying the mixed material from the bottom of the bowl up above the top level either material: m that in addition to the mixing a fluffing up of the material will be brought about. I Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a mixing machine, a bowl, a central. vertical axial shaft, a cross, shaft carriedby said central axial shaft, an agitator carried on said shaft comprising agitating devices having members extending from said. crossl shaft in different directions throughout an arc of'360'' and of such size as to extend below the level of material below said cross shaft and being: freely rotatable, with. contact,

with the material, counter to the maindirection of rotatione'of said agitator.

2'. In combination with a mixing bowl, a substantially vertical rotatable shaft therein; a. horizontal shaft carried by said first named shaft, and agitating devices. mounted onv said. horizontal. shaft having members extending, from said hori'zontal shaft in differ:- ent directions throughout an arc of 360 so-as.

to contact material in the bowl below said horizontal shaft, said agitating devices freely rotatable on said. horizontal shaft, and being s aced on opposite sides of said vertical s aft and being journal'ed on said horizontal shaft to rotate with. contact with materia within saidbowl I 3. In combination with a vertical shaft in a mixing bowl, a horizontal shaft having. an agitating device mounted thereon to which i rotary movement is imparted by contact with material within the bowl whlle being carried by said vertical shaft, said device having members extending from said. horizontal shaft in difierent directions throughout an arc of 360" so as to contact with material in the bowlbelow said horizontal shaft, said device having a balanced structure in which the wei ht of the upper and lower half is evenly cfistributed above and below said horizotal shaft.
